Description

Technical Field

[0001] This utility model relates to the technical field of leather embossing equipment, specifically a leather plate embossing machine. Background Technology

[0002] Leather embossing is the process of creating permanent raised or recessed patterns or textures on the surface of leather using external pressure. Its core principle involves using a heated metal mold (embossing plate) to apply pressure and time to the leather surface, causing physical and chemical changes in its fiber structure, thus forming the pattern on the mold. A plate embossing machine uses a flat, engraved metal plate to press the leather like a stamp, suitable for sheet materials such as leather goods and shoe uppers.

[0003] Currently, during the pressing process of leather embossing machines, the open heating plate leads to high temperatures near the equipment, especially in summer, resulting in a poor production environment. Furthermore, the directly exposed heating plate poses a risk of burns. Therefore, there is an urgent need for an improved technology to solve this problem in the existing technology. Summary of the Invention

[0018] Please see Figure 1-3 This utility model provides a technical solution: a leather embossing machine, including a frame 1, a hydraulic cylinder 2, a support plate 3, a heating plate 4, an embossing template 5, and an exhaust hood 6. The frame 1 has an embossing cavity 7 that is open at both the front and back. A base plate 8 is provided at the bottom end of the frame 1 inside the embossing cavity 7. Several reinforcing plates 15 are provided at the connection between the lower surface of the base plate 8 and the frame 1 to ensure the structural strength of the base plate 8, thereby ensuring the stability of the hydraulic cylinder 2. The hydraulic cylinder 2 is provided on the upper surface of the base plate 8. The piston rod of the hydraulic cylinder 2 faces upward and a support plate 3 is provided through a connecting plate 9. Extension sections 19 are provided on both sides of the support plate 3 to facilitate smooth feeding and unloading of materials and to prevent the leather from falling off due to gravity. Guide sleeves 13 are provided on both sides of the hydraulic cylinder 2. Guide rods 14 are provided on both sides of the lower surface of the connecting plate 9. The guide rods 14 are guided and cooperate with the guide sleeves 13 on the corresponding side. The guide sleeve 13 is used to ensure the stability of the connecting plate 9 and the support plate 3. The frame 1 is equipped with a heating plate 4 at the upper end of the embossing cavity 7. The heating plate 4 is equipped with several heating tubes 16 and thermocouples. The joints of the heating tubes 16 are hidden inside the frame 1. The heating plate 4 is heated by the heating tubes 16. The thermocouples are used for temperature monitoring. The lower surface of the heating plate 4 is equipped with an embossing template 5. The front and rear sides of the frame 1 and the upper part of the embossing cavity 7 are equipped with exhaust hoods 6. Each side of the exhaust hood 6 is equipped with an exhaust port 10. The exhaust ports 10 are connected to the tee joints 12 through connecting pipes 11. The connecting pipes 11 are set on the outside of the frame 1 through the bracket 23 to realize the installation of the connecting pipes 11. The tee joints 12 are also connected to the air inlet of the exhaust fan 21 through the exhaust pipe 20. The exhaust fan 21 is used to extract the hot air from the exhaust hood 6.

[0019] The upper part of the frame 1 is provided with a wiring cavity 17. The frame 1 is connected to the wiring cavity 17 with a small door 18. The wiring cavity 17 is used to install control devices and connectors. The front side of the frame 1 is provided with a controller 22 to control the temperature of the hydraulic cylinder 2, the exhaust fan 21 and the heating tube 16.

[0020] Working Method and Operating Principle: Before use, install two exhaust hoods 6 on the upper end of the embossing chambers 7 on the front and rear sides of the frame 1. Simultaneously, connect the exhaust inlets 10 on one side of the exhaust hoods 6 to the connecting pipes 11. The two connecting pipes 11 are supported on the outside of the frame 1 by brackets 23. The two connecting pipes 11 are connected to tee connectors 12, which in turn are connected to a high-temperature resistant exhaust fan 21 via the connecting pipes 11, allowing hot air to be exhausted outside the workshop. During operation, the piston rod of the hydraulic cylinder 2 lowers the pallet 3, placing the leather on its upper surface. The hydraulic cylinder 2 then raises the pallet 3 and the leather. Depending on the type of leather, the heating element 16 inside the heating plate 4 heats the leather, transferring the heat to the embossing template 5. This ensures the temperature of the embossing template 5 matches the leather, typically between 100℃ and 180℃. The high temperature and the embossing template 5 then emboss the leather surface. During the process, the high-temperature resistant exhaust fan 21 draws hot air from the exhaust hood 6 and through the exhaust pipe 20 and exhaust fan 21 to the outside of the workshop. This utility model has a reasonable structure. Exhaust hoods 6 are provided on the front and rear sides of the frame 1 and on the upper part of the embossing cavity 7. One side of the exhaust hood 6 is connected to the T-joint 12 through the exhaust interface 10 and the connecting pipe 11. The T-joint 12 can be connected to the exhaust fan 21 through the exhaust pipe 20. The exhaust fan 21 and the external pipe are used to exhaust the air to the outside of the workshop, which solves the problem of excessively high temperature around the embossing machine in the workshop, improves the production environment, and avoids burns caused by excessively high temperature at the top when the pallet 3 is lowered and materials are manually added or removed. At the same time, the exhaust hood 6 shields the heating plate 4 to prevent accidental contact and burns, ensuring production safety.

[0021] Any aspects of this utility model not described in detail are well-known technologies to those skilled in the art.
